我使用ClosedXML导出Excel文件,我似乎无法导出Excel文件.每次我点击按钮导出Excel文件(XLSX)我都会收到一个错误.见下文...

    using (XLWorkbook wb = new XLWorkbook())
    {
        wb.Worksheets.Add(dsInput);
        Response.Clear();
        Response.Buffer = true;
        Response.Charset = "";
        Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
        Response.AddHeader("content-disposition", "attachment;filename=" + sFileName + ".xlsx");
        using (MemoryStream MyMemoryStream = new MemoryStream())
        {

            wb.SaveAs(MyMemoryStream, false);

            MyMemoryStream.WriteTo(Response.OutputStream);
            Response.Flush();
            Response.End();
        }
    }

我收到此错误:SecurityException:不允许请求的注册表访问.
